DETAILED DESCRIPTION

As best shown in FIGS. 1 and 2, the present invention may take the form of a system 10 for connecting a pair of trousers 12 to a pair of boots 14. The trousers 12 may include various layers through its thickness to provide various heat, moisture and abrasion resistant qualities so that the trousers 12 can be used as a protective, hazardous duty, and/or firefighter garment. For example, the trousers 12 may include an outer shell 16, a moisture-resistant/vapor-resistant/fluid-resistant barrier 18 located inside of and adjacent to the outer shell 16, and a thermal liner/barrier 20 located inside of and adjacent to the moisture/vapor barrier 18. In the illustrated embodiment the layers 16, 18, 20 are generally annular at the lower end of each trousers leg and arranged such that the moisture barrier 18 is positioned between the thermal barrier 20 and outer shell 16. However, if desired, this configuration can be reversed such that the thermal barrier 20 is positioned between the outer shell 16 and the moisture barrier 18. If desired, an inner liner or inner face cloth (not shown) may be positioned inside the thermal barrier 20 to form the inner-most layer of the trousers 12. Moreover, if desired, the trousers 10 may not necessarily include the thermal barrier 20.

The outer shell 16 may be made of or include a variety of materials, including a flame, heat and abrasion resistant material such as a compact weave of aramid fibers and/or polybenzamidazole fibers. Commercially available aramid materials include NOMEX and KEVLAR fibers (both trademarks of E.I. DuPont de Nemours & Co., Inc. of Wilmington, Del.), and commercially available polybenzamidazole fibers include PBI fibers (a trademark of PBI Performance Fabrics of Charlotte, North Carolina). Thus, the outer shell 16 may be an aramid material, a blend of aramid materials, a polybenzamidazole material, a blend of aramid and polybenzamidazole materials, or other appropriate materials. If desired, the outer shell 16 may be covered with a polymer, such as a durable, water repellent finish (i.e. a perfluorohydrocarbon finish, such as TEFLON® finish sold by E. I. Du Pont de Nemours and Company of Wilmington, Del.). The materials of the outer shell 16 may have a weight of, for example, between about five and about ten oz/yd².

The moisture barrier 18 and thermal barrier 20 (if utilized) may be generally coextensive with the outer shell 16, or spaced slightly inwardly from the outer edges of the outer shell 16 (i.e., spaced slightly inwardly from the lower end of the legs or the waist) to provide moisture and thermal protection throughout the trousers 12.

The thermal barrier 20, if utilized, may be made of nearly any suitable material that provides sufficient thermal insulation. In one embodiment, the thermal barrier 20 may include a relatively thick (i.e. between about 1/16″- 3/16″) batting, felt or needled non-woven bulk or batting material, which can be coupled to a face cloth. The bulk material can also take the form of one or two (or more) layers of E-89® spunlace fabric made of a combination of NOMEX® and KEVLAR® fabric. The bulk material can also, or instead, include aramid fiber batting (such as NOMEX® batting), aramid needlepunch material, an aramid non-woven material, an aramid blend needlepunch material, an aramid blend batting material, an aramid blend non-woven material, foam (either open cell or closed cell), or other suitably thermally insulating materials. The thermal barrier 20 may trap air and possess sufficient loft to provide thermal resistance to the trousers 12. If desired, the thermal barrier 20, or parts thereof, may be treated with a water-resistant or water-repellent finish.

In one embodiment, the thermal barrier 20 has a thermal protection performance (“TPP”) of at least about twenty, and in another embodiment, at least about thirty five. Moreover, in one embodiment the trousers 12 as a whole will have a TPP of at least about twenty, and in another embodiment have a TPP of at least about thirty five, although the trousers 12 may have a relatively low TPP is some cases and may not be particularly thermally insulating.

The moisture barrier 18 may be generally water vapor permeable but generally impermeable to liquid moisture, as well as generally impermeable to the vapor form of harmful/undesirable materials (i.e. non-aqueous materials in one embodiment). The moisture barrier 18 may have microscopic openings that permit moisture vapor (such as water vapor) to pass therethrough, but block liquids (such as liquid water) from passing therethrough. The microscopic openings may be small enough to allow water vapor to pass therethrough, but block vapors/airborne particulates, etc. of harmful materials, which can be larger than water vapor molecules. Thus the moisture barrier 18 can be considered a selective vapor barrier and/or can have selective vapor barrier (or near-complete vapor barrier) qualities, but is generally termed moisture barrier herein in compliance with common industry usage.

The moisture barrier 18 may be made of a microporous material that is either hydrophilic, hydrophobic, or somewhere in between. The moisture barrier 18 may also be monolithic and may allow water moisture vapor transmission therethrough by molecular diffusion. The moisture barrier 18 may also be a combination of microporous and monolithic materials (known as a bicomponent moisture barrier), in which the microporous or monolithic materials are layered or intertwined. The moisture barrier 18 may include a membrane layer bonded to a substrate of flame and heat resistant material on one or both sides thereof to provide structure and protection to the membrane layer.

The moisture barrier 18 can instead, if desired, be generally impervious to all fluids, vapors, aerosols, liquids and gases, including water and water vapor. The moisture barrier 18 can be configured to block harmful materials from passing therethrough. Such harmful materials may include liquids (including chemical warfare agents, biological warfare agents and toxic industrial chemicals), vapors and aerosols of an aqueous or non-aqueous nature (including chemical warfare agents and toxic industrial chemicals), and contaminated particulates (such as biological warfare agents). Examples of chemical warfare agents include soman (GD) nerve agent and distilled mustard (HD) blister agent. Examples of toxic industrial chemicals include acrolein (liquid), acrylonitrile (liquid), ammonia (gas), chlorine (gas), and dimethyl sulfate (liquid).

The moisture barrier 18 may be made of or include expanded polytetrafluoroethylene (“PTFE”) such as GORE-TEX or CROSSTECH materials (both of which are trademarks of W. L. Gore & Associates, Inc. of Newark, Del.), polyurethane-based materials, neoprene-based materials, cross-linked polymers, polyamid, GORE® CHEMPAK® materials, sold by W. L. Gore & Associates, Inc. including GORE® CHEMPAK® Ultra Barrier Fabric, GORE® CHEMPAK® Selectively Permeable Fabric, or GORE® CHEMPAK® Sorptive Fabric, neoprene, rubber, synthetic rubber or other materials. Besides the materials outlined above, the moisture barrier 18 can be made of nearly any material that is generally impermeable to the materials which are desired to be prevented from contact with the wearer, or from contact with inner layers of the garment 12.

In one embodiment, each layer of the trousers 12, and the trousers 12 as a whole, may meet the National Fire Protection Association (“NFPA”) 1971 standards for protective firefighting garments (“Protective Clothing for Structural Firefighting”), which are entirely incorporated by reference herein. The NFPA Structural Firefighting standards specify various minimum requirements for heat and flame resistance and for tear strength. For example, in order to meet the NFPA standards, each of the outer shell 16, moisture barrier 18, and thermal barrier 20 individually, and the trousers 12 as a whole, must be able to resist igniting, burning, melting, dripping, separation and/or shrinking by more than 10% in any direction at a temperature of 500° F. for at least five minutes. Furthermore, in order to meet the NFPA standards, the combined layers of the trousers 12 must provide a thermal protective performance rating of at least thirty five.

NFPA 1971 standards include a Chem/Bio Option, also known as the CBRN (chemical, biological, radiological and nuclear) Option (the entire contents of which are hereby incorporated by reference) which provides specifications that protective ensembles must meet in order to be certified under that Option. For example, the Chem/Bio Option specifies that the garment must pass a MIST test (Man In Simulant Test). In one case the MIST test essentially consists of introducing the garment into a chamber filled with a vaporized test material (such as oil of wintergreen). Absorbent pads are placed on the wearer and/or inside the garment. After the garment has been exposed to the vaporized material for a sufficient period of time, the garment is removed from the chamber. The absorbent pads are removed and analyzed to determine how much of the vaporized test material they have absorbed. Thus, the garment disclosed herein may instead, or also, be arranged to meet the Chem/Bion Option standards.

However, the trousers 12 may include various arrangements of liners/materials, as desired, in which the various layers described herein are included, omitted, and/or rearranged. For example, the trousers 12 may lack any thermal barrier 20, or lack any moisture barrier 16, or include only an outer shell 12 and lack other layers, etc., or may take on various other configurations as desired to meet various other NFPA requirements, and need not even necessarily be NFPA compliant.

The boots 14 may also, in one embodiment, be compliant with NFPA regulations. Each boot 14 may include an outer layer 22 made of a relatively strong, durable and abrasion-resistant material, such as leather, synthetic leather, rubber, synthetic rubber, fibrous materials such as NOMEX® or KEVLAR® fibers, or various other materials as desired. Each boot 14 can include various inner layers as shown, for example, in FIGS. 3-9. In one embodiment, each boot 14 includes a fluid barrier/moisture barrier 24 and a thermal barrier 26 positioned inside the outer layer 22. Each of these layers 22, 24, 26 may be generally annular about upper portions of the boot 14. The moisture barrier 24 and thermal barrier 26 may be made of the same or similar materials and/or have the same qualities as those outlined above for the moisture barrier 18 and thermal barrier 20 of the trousers 12. However, the thermal liner 26 for the boots 14, if utilized, may not necessarily be fire resistant, and can be made of a nonwoven synthetic fabric such as CAMBRELLE® material sold by Camtex Fabrics Limited of Cumbria, United Kingdom, with a moisture barrier attached thereto. FIGS. 3-9 illustrate the moisture barrier 24 positioned between the outer layer 22 and the thermal barrier 26; however, if desired, the position of these layers may be reversed such that the thermal barrier 26 is positioned between the outer layer 22 and the moisture barrier 24.

In one embodiment, the moisture barrier/fluid barrier 24 is generally continuous and extends throughout the boot 14 to provide continuous moisture/vapor/fluid protection thereto. Similarly, the moisture barrier 18 of the trousers 12 may be generally continuous and extend throughout the trousers 12 to provide continuous moisture/vapor/fluid protection thereto. By “continuous” it is meant that continuous moisture/vapor/fluid protection is provided; not necessarily that only a single seamless moisture/vapor/fluid barrier layer is provided. In other words, multiple pieces of a moisture barrier 18/24 can be coupled together in a moisture tight/vapor tight/selectively vapor tight manner and still be continuous as intended herein (although a one-piece moisture could also of course be utilized and considered continuous). If desired, the moisture barrier 22 and thermal barrier 26 of the boots 14 can be made of a differing material than the particular moisture barrier 18 and thermal barrier 20 of the associated trousers 12.

Each boot 14 may include a pair of pulls 28 (FIG. 2) on opposite sides thereof to aid the wearer in pulling the boot 14 over his or her feet. Each boot 14 may include a durable, puncture-resistant tread or sole 30 on its bottom surface thereof and made of a differing material than the outer layer 22, or moisture barrier 24 or thermal barrier 26. Each boot 14, and the tread 30, is thus designed to provide the outer-most surface protecting a wearer's foot to protect from abrasion, wear, and rough or sharp materials (such as broken glass, metal shards, etc.) on ground surfaces.

Each boot 14 includes a body portion 32 and an upper portion, flap or flap portion 34 forming, and/or extending away from, an upper edge 36 of the body portion 32. When folded as shown in FIG. 3, the flap portion 34 defines a space 38 between the flap portion 34 and the body portion 32. In the illustrated embodiment, the flap portion 34 includes an outer protective portion 22 a that can be of the same (or differing) material as the outer layer 22 of the boot 14. If desired, the flap portion 34 may include one or more of the inner layers 24, 26 of the boot 14 (or other inner layers, if included). For example, in the embodiment of FIGS. 3-9, the flap portion 34 includes a portion 26 a of the thermal barrier material 26. In the illustrated embodiment, the thermal barrier 26 a of the flap 34 is continuous with the thermal barrier 26 of the body portion 32. However, if desired, the thermal barrier 26 a in the flap 34 can be separate and discrete from the thermal barrier 26 in the body portion 32 of the boot 14. Alternately, if desired, the thermal barrier 26 a can be omitted from the flap 34.

As shown in FIG. 3A, in one embodiment the flap 34 includes a moisture barrier portion 24 a. In the embodiment of FIG. 3A, the flap moisture barrier 24 a is continuous with the body moisture barrier 24, but the moisture barriers 24, 24 a can be made of separate pieces of material if desired.

As best shown in FIGS. 2 and 3, the moisture barrier 18 of the trousers 12 includes a generally annular extension portion 40 which extends away (generally upwardly in the configuration of FIGS. 2 and 3) from the lower edge of the trousers 12. A distal end of the extension portion 40 is received in the space 38 between the flap portion 34 and the body 32 of the boot 14. In the illustrated embodiment, the end of the extension 40 is folded about itself under the flap portion 34, as shown in FIGS. 2-4, to form a two-ply folded section of the barrier material 42. The folded section 42 can be omitted but may aid in sealing the boot 14/trousers 12 connection, as will be described in greater detail below.

The moisture barrier extension 40 includes a pair of fastening components 44 a, 46 a on opposite sides thereof. As can be seen in FIG. 3, fastening component 44 a on the radially outer surface of the extension portion 40 releasably engages a corresponding fastening component 44 b at or adjacent to the end of the flap portion 34. Fastening component 46 a on the radially inner surface of the extension portion 40 releasably engages a corresponding fastening component 46 b at or near the upper edge 36 of the body 32 of the boot 14.

In the illustrated embodiment, each fastening component 44 a, 44 b, 46 a, 46 b takes the form of a zipper/zipper track such that a zipper pull (i.e., see zipper pull 50 of FIG. 2 which is associated with fastening components 44 a, 44 b) can be extended about the periphery of the fastening components 44 a, 44 b, 46 a, 46 b to couple or decouple the associated fastening components. The fastening components 44 a, 44 b, 46 a, 46 b can be configured to form a fluid and/or vapor tight seal when closed (i.e., in the case of a zipper the zipper is fluid/vapor tight), or if desired the components 44 a, 44 b, 46 a, 46 b may not form a seal when closed. Moreover, the fastening components 44 a, 44 b, 46 a, 46 b can take any of a wide variety of other forms besides zippers such as hook-and-loop fastening material (i.e., VELCRO®), a plastic zipper seal utilizing linear beads such as that analogous to a seal found on ZIPLOC® plastic bags (also known as “press-to-close” zippers, or reclosable or releasable closures), snaps, hooks, clasps, magnets, frictional engagement, interlocking shapes or the like.

The arrangement shown in FIGS. 2 and 3 provides a relatively vapor tight/fluid tight/selectively vapor tight arrangement to the wearer. In particular, instead of having trousers which are open at the bottom in which an annular gap is formed about each boot 14, the moisture barrier extension 40 extends from the radially inner surface/lower edge of the trousers 12 to the boot 14, and is coupled thereto. Moreover, each boot 14 includes its own moisture barrier 24 that is coupled to the moisture barrier extension 40 in a fluid tight/vapor tight manner via the fastening components 46 a, 46 b. In this manner, when harmful vapors are introduced into the surrounding environment, such vapors are prevented from entering the boot 14 and/or inner cavity of the legs of the trousers 12. The wearer can thus remain relatively protected from harmful vapors and the trousers 12/boot 14 form a sealed connection/cavity therebetween. Moreover, should any vapor or moisture penetrate through the outer layer 22 of the boots 14, the moisture barrier 24 within the boots 14 helps to protect the wearer from contamination.

Because the moisture barrier extension 40 is trapped or sandwiched between the flap 34 and the body 32 of the boot 14, a relatively vapor tight connection is formed therebetween, and in particular the folded portion 42 can be compressed by the folded portion 34, and held in place by the fastening components 44 a, 44 b to improve the seal provided by the folded portion 42. In the embodiment of FIG. 3A, the folded portion 42 is pressed into contact with, and directly engages, the moisture barrier 24 of the boot 14 to aid in sealing of the boot 14.

Moreover, the fastening components 44 a, 44 b, 46 a, 46 b also help to mechanically and/or fluid-tightly securely couple the moisture barrier extension 40 to the boot 14, thereby further protecting against vapor penetration. If desired, more complete vapor protection can be provided by using vapor-tight fasteners (at least for fastening components 46 a, 46 b), and ensuring the fastening components 46 a, 46 b (i.e., their fastener flaps) are attached in a fluid-tight manner (i.e., any stitching is secured by vapor-tight sealing tape or the like, or adhesives or other non-penetrating methods are used to attach the fastening components 46 a, 46 b). The coupling arrangement 10 shown herein, in combination with various other protective features, may provide a garment/ensemble which passes the MIST test, and more broadly, meets the Chem/Bio Option of NFPA 1971 standards.

In order to detach the boot 14 and trousers 12, the fastening components 44 a, 44 b are first separated, as shown in FIG. 4. Next, as shown in FIG. 5, the flap portion 34 is unfolded until the flap portion 34 extends vertically upwardly from the upper edge 36 of the body 32 of the boot 14. Next, the extension portion 40 is inverted (i.e. turned inside-out), such as by partially extracting the boot 14 out from the trousers 12, as shown in FIG. 6. Inverting the extension portion in this manner may help to provide easier/direct access to the fastening components 46 a, 46 b. Next, as shown in FIG. 7, the fastening components 46 a, 46 b are decoupled and, as shown in FIG. 8, the boot 14 is completely separated from the trousers 12.

Next, as shown in FIG. 9, the boot 14 can be configured for use as a stand alone boot; i.e., for use in a manner in which the boot 14 is not sealingly coupled to the trousers 12. In particular, the fastening component 44 b of flap portion 34 can be releasably coupled to the fastening component 46 b of the body 32 of the boot 14 to provide a finished appearance and generally sealed functionality to the boot 14. For example, in the illustrated embodiment the outer portions 22, 22 a (which can be made of the same material and have the same appearance) form the entire outer surface of the boot 14 (except of the fastening components 44 b, 46 b) providing a continuous and finished appearance. In this manner, the boot 14 can be used with various other trousers, including trousers which do not include the moisture barrier extension 40 or otherwise contribute to form a generally vapor-tight or vapor-resistant connection with the boot 14.

The boot 14 shown herein thus has dual use capability as it can be used in standard firefighter trousers or other protective garments when a moisture or fluid tight, vapor-tight or vapor-resistant connection is desired. In order to couple the boot 14 to the trousers 12/moisture barrier extension 40, the steps shown in FIGS. 3-9 are carried out in reverse. It should be noted that the pulls 28 (FIG. 2) are located on, or protrude outwardly from, a radially inner surface of the boot 14. In this manner, the pulls 28 are spaced away from the flap 34 and fastening components 44 b, 46 b, and do not interfere with the coupling of the moisture barrier extension 40 to the boot 14.

Thus, the system 10 may utilize boots 14 that are detachable from the trousers 12 so that the trousers 12 and boots 14 can each be separately cleaned, maintained, and replaced as desired. Moreover, the boots 14 can be used as a stand-alone components with other trousers which do not require a vapor-tight or vapor-resistant connection therewith (i.e., for non-CBRN suits).

The system and method shown herein can also be used to form vapor/fluid-tight or vapor/fluid-resistant connections at other portions of garments. For example, the system can be utilized to attach gloves to the sleeve of a coat; a hood to the body of the coat; a coat to a pair of trousers (i.e. about the waist of the coat and trousers, etc.), and make other connections in the same manner as described above and shown herein. The method and structure disclosed herein can be used to detachably, yet sealingly, attach various other garments and parts thereof together to provide the advantages specified herein.
